Specification of Letters Patent.

Patented May 23, 1911.

Application led December 20, 1909. Serial No. 534,208.

To all whom t may concern:

Be it known that I, LOUIS ROSEN, a subject of the Czar of Russia,residing at Chicago, county of Cook, and State of Illinois, haveinvented certain new and useful Improvements in Propelling Means, ofwhich the following is a specification.

My invention relates to improvements in propelling means especiallyadapted for use in propelling vehicles or boats, and has for its objectthe production of simple and eilicient manually operated propellingmeans.

The invention consists in the combination and arrangement of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Figure 1 is a sectional elevation of a wagon embodying my invention, andFig. 2 is a top plan view of the same with parts broken away andremoved.

The preferred form of construction as illustrated in the drawingscomprises a suitable frame adapted to support the driving mechanism andan operator. At its front the frame 1 is pivoted on a vertical shaft 2carried centrally by the front axle 3 on which front wheels 4L arerotatably mounted. At its upper end shaft 2 carries a bevel gear 5meshing with a bevel gear 6 having a universal joint connection with asteering rod 7. Steering rod 7 is supported in a suitable standard 8having bearings 9 therefor. At its upper end rod 7 carries a hand wheel10 in convenient position for manipulation by an operator seated uponthe seat 11.

At the rear the frame 1 is supported upon a rotatable axle 12 carryingsupporting wheels 13 fixed thereto. A pair of horizontally disposedoperating levers 14 are fulcrumed in frame 1 as at15 and carryadjustable weights 16 screw threaded thereon. Each of said leverscarries a segment gear 17 secured thereto coaxially with fulcrum 15.Elongated gears 18 are mounted in suitable brackets on frame 1 and meshwith segment gears 17 for a portion of their length. The other portionsof gears 18 mesh with driving gears 19 fixed to shafts 20 which carrysprocket wheels 21. Sprocket wheels 21 are connected by means ofsprocket chains 22 with sprocket wheels 22 loosely mounted on rear axle12. Ratchet wheels 23 are fixed to axle 12 adjacent sprocket wheels 22.and pawls 211 are provided on sprocket wheels 22 to engage ratchetwheels 23 and cause intermittent driving connections between theirsprocket wheels and said axle. Each of the levers 14 is provided with adownwardly extending bow member 25 carrying pedals 26 located inoperative relation to seat 11. Rearwardly extending bearing members 27are secured to bows 25 and rest upon eccentrics 28 fixed to rear axle12.

Eachof the bearing members 27 is provided with downwardly extending sideplates 29 adapted to engage over the sides of said eccentrics to retainsaid bearing members in supporting wheels 13 by means of pawls 24C' thusserving to propel the wagon in a forward direction. Eccentrics 28 serveto elevate levers 14 during their inoperative stroke and are set on axle12 in opposed angular position so as to cause alternate operations ofsaid levers.

By adjusting weights 16 away from the fulcrums of their levers theinitial starting of the wagon is facilitated thus rendering the deviceadjustable to the relative strengths of operators. By adjusting weights16 to di'erent distances on their respective levers the said levers maybe adjusted to the relative strengths of the dierent legs of theoperator.

To start the device the operator may elevate the operating levers withhis arms and depress said levers. This will serve to start the deviceand when once started pressure applied to the pedals will continue themotion. To insure freedom of action the gearing connecting with the rearaxle should be such as to cause the eccentrics to travel at a highenough speed to prevent interference with the downward movements of theoperating levers.

Vhile I have illustrated and described the preferred form ofconstruction for carrying my invention into effect the same is capableof different applications such as to boats,

5 avail myself of such variations and modifications as come within thescope of the appended claims. a v

Having described my invention what I claim as new and desire to secureby Letters l0 Patent is l. A propelling device comprising a frame; awheeled running gear for said frame comprising an axle having wheelssecured thereto; a pair of levers fulcrumed in said frame;

an internal segment gear secured to each of said levers co-axially withits fulcrum; an elongated gear having a portion meshing with saidsegment gear; a drivin'g gear meshing with the other portion of saidelongated gear; a sprocket driven by said driving gear; a sprocketloosely mounted on said axle; a pawl and ratchet connection between saidlast named sprocket and said axle; a sprocket chain passing over saidsprockets; pedals on said levers; means on said axle for alternatelyelevating said levers; and a seat for an operator located in operativeproximity to said pedals, substantially as described.

2. A propelling device comprising a frame; a wheeled running gear forsaid frame comprising an axle having wheels secured thereto; a pair oflevers fulcrumed in said frame; an internal segment gear secured to eachof said levers co-axially with its fulcrum; an elongated gear having aportion meshing with said segment gear; a driving gear meshing with theother portion of said elongated gear; a sprocket driven by said drivinggear; a sprocket loosely mounted on said axle; a pawl and ratchetconnection between said last named sprocket and said axle; a sprocketchain passing over said sprockets; pedals on said levers, oppositelydisposed eccentrics on said axle; bearing members secured to said leversand bearing upon said eccentrics; and a seat for an operator located inoperative proximity to said pedals; substantially as described.

3. Apropelling device comprisinga frame; a wheeled running gear for saidframe comprising an axle having wheels secured thereto; a pair ofhorizontally disposed levers fulcrumed in said frame; adjustable weightson said levers; an internal segment gear secured to each of said leverseo-axially with its fulcrum; an elongated gear having a portion meshingwith said segment gear; a driving gear meshing with the other portion ofsaid elongated gear; a sprocket driven by said driving gear; a sprocketloosely mounted on said axle; a pawl and ratchet connection between saidlast named sprocket and said axle; a sprocket chain passing over saidsprockets; pedals on said levers; oppositely disposed eccentrics on saidaxle; bearing members secured to saidl levers and bearing upon saideccentrics; and a seat for an operator located in operative proximity tosaid pedals, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
